Package on npm

API

• setBoolean
• setNumber
• setString

setBoolean(data, [fallback])

Check if data is a Boolean

If yes, return data otherwise return fallback

Argument	Action
data	the tested data
fallback	optional fallback, default to false

const setBoolean = require('set-funcs/set-boolean')
 
function test(opts) {
  opts = opts || {}
 
  // option silent will be `true` if not defined
  opts.silent = setBoolean(opts.silent, true)
}

---

setNumber(data, [fallback], [min], [max])

Check if data is a Number

If yes, return data otherwise return fallback

data can be clamped between min and max

Argument	Action
data	the tested data
fallback	optional fallback, default to 0
min	optional min. If defined, data will be clamped to it
max	optional max. If defined, data will be clamped to it

const setNumber = require('is-funcs/set-number')
 
function test(opts) {
  opts = opts || {}
 
  // option `delay` will be `50` if not defined
  opts.delay = setNumber(opts.delay, 50)
 
  // option `time` will be 25 min
  opts.time = setNumber(opts.time, 50, 25)
}

---

setString(data, [fallback], [allowed])

Check if data is a String

If yes, return data otherwise return fallback

allowed can be a string or an array of accepted values. If data is not found in allowed, the fallback is returned

Argument	Action
data	the tested data
fallback	optional fallback, default to ''
allowed	optional allowed. String or Array of accepted values

const setString = require('is-funcs/set-string')
 
function test(opts) {
  opts = opts || {}
 
  // option `ignore` can be 'resize' or 'scroll', fallback to 'resize'
  opts.ignore = setString(opts.ignore, 'resize', 'resize scroll')
 
  // using the array form
  opts.ignore = setString(opts.ignore, 'resize', ['resize', 'scroll'])
}
